TP: What are the limitations of the existing peer-review system?

Dr. Kimball: Limitations of the existing peer-review system include the lack of a standardized and transparent review process, inherent biases that may affect how reviewers judge manuscripts, and insufficient time and training for reviewers. Formal guidelines should be developed for peer review with metrics to ensure that they are being followed, and reviewers should be blinded to the author names and affiliations until after an editorial decision is made. This may help to improve objectivity and transparency. Moreover, a high-quality review takes time to complete and is largely unincentivized, and identification of reviewers with scientific expertise can be challenging. One strategy to address this is for senior reviewers to invite junior colleagues to collaborate on reviews and to mentor them in the process.

TP: What reviewers have to bear in mind while reviewing papers?

Dr. Kimball: When providing criticism, it is critical that reviewers remain sensitive to the huge amount of time and effort that authors put into their research and in preparing the manuscript. Comments should be constructive, kind, and based on science. For manuscripts that are not accepted, comments made during peer review can be especially useful as authors seek to revise their manuscript or plan future research. A platform to allow discussion between authors and reviewers may be valuable in those cases.

It acts as a critical checkpoint, where experts in the field evaluate a study's methodology, findings, and relevance before publication. This process helps identify errors, biases, or unsupported conclusions, promoting scientific integrity and reliability. Peer review also encourages authors to improve clarity and rigor, enhancing the overall quality of the work. By filtering out flawed or unsubstantiated research, peer review safeguards the scientific literature and supports informed decision-making in clinical practice, policy, and future research. It is a cornerstone of academic and scientific advancement.

TP: What are the limitations of the existing peer-review system?

Dr. Pattnaik: It can be time-consuming and is sometimes influenced by reviewer bias or conflicts of interest. Variability in reviewer expertise and inconsistent feedback can affect the fairness and quality of evaluations. To improve peer review, steps can include adopting open or double-blind review models, providing reviewer training, using standardized evaluation tools, and incorporating post-publication review. Increased recognition and incentives for reviewers, along with greater diversity in review panels, can further enhance the system’s fairness, efficiency, and reliability.

TP: Is it important for authors to disclose Conflict of Interest (COI)?

Dr. Pattnaik: Yes, disclosing COI is essential for maintaining transparency and trust in research. A COI can influence study design, data interpretation, and reporting, potentially leading to biased conclusions that favor a sponsor or personal interest. Even perceived COIs can undermine credibility. Full disclosure allows readers and reviewers to assess the objectivity and reliability of the findings, helping protect the integrity of scientific literature.

Srujan Ganta

Dr. Srujan Ganta is a cardiothoracic surgeon at Rady Children’s Hospital in San Diego, California (RCHSD), specializing in care for pediatric and congenital heart conditions. His academic and training journey includes an undergraduate degree in Biochemistry and a medical degree with research distinction from the University of Alberta. He then completed a six-year integrated cardiothoracic surgery residency at the Mazankowski Heart Institute and Stollery Children’s Hospital, earning certification in Cardiac Surgery (FRCSC). He further refined his expertise with a fellowship in pediatric and adult congenital cardiac surgery at the Medical University of South Carolina. His clinical interests span congenital and adult congenital heart surgery, heart and lung transplantation, valve and coronary artery surgery, adult cardiac surgery, and cardiac electrophysiology (including pacemaker implantation). His current research focuses on impactful areas like surgical strategies for single ventricle palliation post-PDAS, optimizing Tetralogy of Fallot repairs, and novel techniques in TAPVR correction. Learn more about him here.

According to Dr. Ganta, when reviewing academic papers, a reviewer should first embody key qualities to drive scientific progress: act as a constructive partner (not just a critic), bring deep subject-matter expertise to assess work insightfully, and look beyond the text to grasp a study’s underlying value and potential impact. Curiosity, fairness, and open-mindedness are essential—reviewers must acknowledge their own biases, prioritize high-quality research regardless of its style or origin, and rigorously check for methodological flaws, logical gaps, or errors, all while conveying concerns respectfully. Ultimately, their role is to elevate research quality, uphold journal standards, and foster collaboration, innovation, and academic integrity.

In addition, Dr. Ganta reckons that reviewers must commit sufficient time to thoroughly evaluate papers and their references, managing their schedule to avoid rushing. Critically, they must guard against personal or institutional bias, ensuring assessments focus solely on a manuscript’s scientific merit and findings—protecting research integrity and contributing meaningfully to its advancement.

“TP should be commended for the high quality of their manuscripts which have provided well-tempered opinions on a wide range of topics within paediatric cardiovascular sciences. I review for TP as it aligns with my commitment to advancing high-quality, clinically relevant research that has impact globally. The journals’ ability to bridge bench to bedside research resonates with my interest in promoting evidence-based care. Contributing as a reviewer allows me to support fellow researchers while staying engaged with emerging developments in our profession. I value the opportunity to uphold scientific integrity and contribute to the growth of a respected research platform,” says Dr. Ganta.

Grigorios Petrousis

Dr. Grigorios Petrousis is a physician with an academic and clinical background in Internal Medicine and Gastroenterology. He obtained his medical degree in Greece and subsequently completed a Master of Science in Deontology and Ethics in Biomedical Sciences. He is currently a resident doctor at the Center for Digestive Health at Karolinska University Hospital in Stockholm, Sweden, following prior clinical training in both Greece and Sweden. In parallel with his residency, he serves as a sub-investigator in clinical and observational studies, with research interests centered on Inflammatory Bowel Diseases and intestinal ultrasound. An active peer reviewer for several international medical journals, he integrates his clinical practice with academic endeavors, driven by a particular interest in gastroenterology, immune-mediated diseases, medical ethics, and the advancement of evidence-based medicine.

TP: Why do we need peer review?

Dr. Petrousis: Peer review is the cornerstone of scientific integrity. It ensures that published research is not only methodologically sound but also clinically meaningful and ethically conducted. As clinicians, we rely on evidence to guide patient care; peer review provides a safeguard that this evidence is critically assessed before entering practice. Moreover, the process promotes dialogue between authors and reviewers, often strengthening the manuscript. For me, peer review reflects the collaborative spirit of medicine and science—ensuring that we build knowledge on a solid, reliable foundation.

TP: The burden of being a scientist/doctor is heavy. How do you allocate time to do peer review?

Dr. Petrousis: Balancing clinical duties, research, and personal life can indeed be challenging. I approach peer reviewing as both a responsibility and a learning opportunity. To manage time effectively, I usually schedule reviews during quieter periods, such as early mornings, weekends, or study blocks, when I can focus without clinical interruptions. I also remind myself that reviewing is not just giving back to the scientific community; it is a way to sharpen my own critical thinking, stay updated with new findings, and refine my academic writing. This mindset helps transform reviewing from a “burden” into an intellectually rewarding activity.

TP: Why is it important for a research to apply for institutional review board (IRB) approval?

Dr. Petrousis: IRB approval is essential to safeguard the rights, dignity, and well-being of research participants. Ethical oversight ensures that risks are minimized, informed consent is respected, and vulnerable populations are protected. Without this process, research risks losing credibility and public trust, and more importantly, it may expose patients to harm. From a scientific perspective, the omission of IRB approval undermines the validity of the work, making it unlikely to be published or accepted within the medical community. In my view, IRB approval is not a bureaucratic step, but rather a fundamental pillar of ethical and responsible research.

In addition, he has an interest in mentoring and training the STEM workforce, especially future physician-scientists. Connect with him on LinkedIn.

TP: What role does peer review play in science?

Dr. MacQuarrie: I think of peer review as ideally having a rather grandiose role in science – it helps maintain the integrity and validity of scientific research by providing unbiased and fair feedback on science before it’s disseminated to the wider world. That, of course, is its role in a perfect world – scientific publication hasn’t always been subject to peer review, there’s a ‘reproducibility’ crisis in a lot of science, there’s a rise in preprinting manuscripts, and ‘unbiased’ and ‘fair’ certainly aren’t always the main focus of all reviewers. That being said, I do think helping ensure the validity of the scientific record, as it were, is a great aspirational goal for peer review.

TP: What are the limitations of the existing peer-review system?

Dr. MacQuarrie: Existing peer-review systems suffer from a couple of issues: occasionally frustratingly opaque decisions/decisions in a vacuum, lack of compensation for a task that can take a significant amount of time in a publishing system that often reaps substantial financial rewards (making the inequity apparent), and reviewers who may not review your work in a measured and fair manner (or give it the time and attention it deserves). Some of those issues I think could be alleviated if trainees were consistently trained in how to fairly and appropriately provide reviews; I like to reiterate to trainees that their job as a reviewer is not just to find the holes in a manuscript; it’s also to recognize what’s good about it! When it comes to issues like compensation, I do think it’s something the scientific and medical community – and scientific publishers – need to seriously grapple with. Medicine in particular is rather famous for expecting uncompensated work from those who have careers in it, but I just don’t think that’s sustainable from a systems perspective.

TP: Peer reviewing is often anonymous and non-profitable. What motivates you to do so?

Dr. MacQuarrie: In the present day, peer review is an integral part of being a good ‘scientific’ citizen. I hope others will help to peer review for me, just as I do for them - so there’s certainly an element of altruism there. In addition to that, I also find that peer reviewing ends up with me seeing a variety of manuscripts that I otherwise might not, so I appreciate the chance to broaden my horizons as well.
